Probably not, if your coach is controlled with the BMPro system. My 2021 Axis shows 10A fused circuits protecting each of the grey and black heating pads. Since as I recall each pad draws about 5A, then with two pads on each 10A fuse, it is likely to blow.
Maybe you could up the fuse to 15A which should be safe since it is 14 gauge wire that feeds the pads.
OTOH, I doubt if you need more than 5A on each tank.
